Patients with vocal cord nodules can eat fish, as fish is a common food and it does not have direct side effects or exacerbate existing symptoms related to vocal cord nodules, nor does it conflict with medications used to treat vocal cord nodules. It is recommended that patients with vocal cord nodules adopt a lighter diet, avoid spicy and irritating foods, and it is advised not to smoke or drink alcohol. Regular check-ups at an otolaryngology department are also recommended. If symptoms like hoarseness occur, it is necessary to combine treatment with traditional Chinese medicine taken orally and nebulization therapy. During the treatment process, regular check-ups are required to observe the treatment effects, and a small number of patients may need surgical treatment.
